we're not aligning the transmitter, only the receiver! :-)Heck, the old "TV men" could align NTSC (analog) color TVs with a 5 MHz scope. The color subcarrier signal frequency was 3.579545 MHz.
One does need, at least, a calibrated sweep generator and a marker signal to align the FM, a good, accurate VTVM -- and a frequency counter's nice to have, too, but folks aligned (mono) FM receivers in the 1950s, with 1950s "repair person" grade electronics, to good effect.
caveats:
1) I don't mean to imply that it's easy, especially for a nonspecialist. I "know" how to do it, but I do leave it to the pros.
2) MPX stereo is yet more sophisticated.
all the best,
